@pipes and in other like connections, to cut-` in conjunction with 'the specification and 'To all whom t may concern.' u Y v Be it known that I, JOHN' lW. CALHOUN,

through. y 415in object of the invention fis to provide .JOHN-w. cALnoUiinjor onns'inja, rnnnsrnviima.:

Application le. Januar/y lfllil, Seriali'fo; y i' a citizen ot the United States, residing at Chester, in the county of Delaware and State/ of Pennsylvania, have invented new` and useful improvementsA in Stopcoclsfofwhich the following is a specification.v

My present invention ielatesf'to stop cocks, and particularly Vto* devices of? thisV characterl adapted to be used in water service oli the passage of liquid for fluid 'there-l a stop cock of the turning plug type which is so constructed'that'aside vtroni the inlet v and outlet passages the only opening in the Case is that through vwhich the turning plug is'inserted when fitted in place,'-an`d to provide a suitable packing to insure' against leakage at this point.

A further object residesy in arranging'a bearing by which the turning plug is held against excessive tightening within the case to thus insure easy working at all times, and in providing for lubrication at this bearing.y

`Yet another object is to so construct the parts that the casing structure lends itselil particularly to embodimentin an angle cock.

With the above andother objects in view which will be apparent from the drawings claims, this inventionV includes certain novel 'features of construction and combinations of parts which will now be set forth.

In the drawings:

vFigure 1 is a view partly in section show-y l ing'the adaptation of my invention in an angle stop cock. p Y

Fig. 2 is a view similar to Fig. l'showing a modified application.' l

In the preferred embodiment the case 1 i so formed that the inlet passage 2 and the outlet passage 3 are substantially at right angles, the flow of liquid or fluid being in the direction indicated by the arrows.. In this form of the case or body,-an inner shell 4 is cored and is reamed to talrethe turning plug 5, and around the inletI and outlet pas- 1 sages the casing is threaded lor otherwise, formed for attachment inv a position for use. At one side the shell l merges into the lines 0I" the body, and at this point the out:

let passage?) communicates with the interior of the shell, while at the opposite side a fluid port 6 is provided within the body and A Specification of Letters Patent. u

The turning plug is reduced iat its'outer end Jto-:torin stem ll,` with ashoulder 12;at

the` point ci ,-jointure, and the 'stern is given a polygonalshapel at'13,at its Outer end, 'so that-thel plug ymay', be more read-ily.,turned.` v vThe reamed opening within shell" is" preferably made l somewhatr tapered I' turningpl'ugy '5 is-A given 'a .c'orresp'endingv .shape sov thfatltl'ie plug -will'not 'bind' when" seated4 on bearingpintle;8,.and'*by'reason ofV A the fact that the inner end of the plugis contained entirely within the casing ork body there is no posibility of leakage 'at this point .even though the turning plug be comparatively free within the shell andV suicientlyloose for ready turning. However, as `the cored and reained opening oit the shell must be closed after the turning-- plug is inserted, the casing or body is externally screw threaded around this open- I 9o fbe turned onto this threaded portion and to ing, a packing gland 111 beingV provided to compressfa gasket 15 0f leather or other f suitable -material with suiicient packing force against stein 11 and the inner wall of shell a that a tight joint is formed at this point, Vthe gasket being held. between glandlll and shoulder l2.

By providing thebearingsupport for-the y turning plug, as above outlined, this plug is .l

given a ioating mounting;V however, Ait is preferable that the bearing, be lubricated. at pintle 8, and around the lower portion .of

the turning plug, to accomplish which pur` 'Y pose a duct 16 is formed in the plug extend'- Y jing from bearing to passage 10.

' ln'the embodiment illustrated in Fig. v2, 4the principle of construction and the pur@ poses to be accomplished are substantially the same as with the disclosure in Fig. l;

however, the case or body 17 is constructedwith the inlet and outlet passages 18 and 19 in alinement, and in this instance the shell.'l 'Y fio ber of dierent connectionsdue to its design and. ease of operation, and V.Which eliminates the faults found in the usual types of stop cocks.` Therefore, While I have herein set forth only certain specific embodiments, Vand -have mentioned limited posssible modifications, I desire to have it understood that in practice I do not Wish to i i limit myself to such specific details as here- Y the scope of the invention p appended claims. y,

turning plug and having a bearing pintle in particularly set forth, but may' resort toy any practical modifications vfalling Within as defined in the I claim: A c e VLVA stop cock including With acase having inlet and outlet passages, said lcase being,r provided withv an opening to,I receive a atthe, bottom of said opening, a yturning plug having,` a passage bearingpintle, and a'ductleadin'g from the therethrough Y mountedY in the opening to turn on said u passage of said turning plug to `discharge at the bearing ofsaid pintle.

2.

packing members by whichV the open end of Ysaid shell is closed aroundsaid Vturning plug, said shell having a lbearing plintle at the fclosed end thereof v and said turning. plug lbeing providedv with aA bearingto lit saidpintle, and a ductv leading from the passage ofsaid' plug tothe lbearing thereof.

3. A stop cock including Withfa ycase formed to provide right angularly opening inletj'and outlet passages and having a f shell therein reamed to'talze a turning plugV and into Which one ofvsaid passages opens, l

Y said shell being provided vvi'tha' side open'- e ing in line with the passageopening thereinto, and a turningY plug mounted in ,said

shell andhaving a passage lined up; with the side opening thereof and the' passage of the casing openingl thereinto.
